ALEXANDER LONG, OF BAIRDSIOWN, OHIO.

CIRCULAR-SAW JOINTER.

SPECIFICATION forming part Of Letters Patent No. 256,011, dated April 4,1882.

Application filed January 11, 1882. (No model.)

To all whom it may concern:

Beit known that I, ALEXANDER LONG, a citizen of the United States,residing at Bairdstown,in the county ofWood and State of Ohio, haveinvented certain new and useful Improvements in Saw Gages and Jointers;and I do hereby declare that the followingis a full, clear, and exactdescription of the same, reference being bad to theaccompanyingdrawings, forming part of this specification.

My invention relates to improvements in circular-saw gages and jointers;and the novelty consists in the means for securing and holding the filein the jointer-frame, in the adjustment of the same, in the screwsarranged in the forked or bifurcated end of the main frame, and thebearing-screws for steadying the sawblade while the teeth of the sameare being filed, all as will be hereinafter more fully set forth.

In the annexed drawings, to which reference is made, Figure 1 is arepresentation of a longitudinal section of my saw-jointer, showing afile placed therein; and Fig. 2 is a plan view of the same.

The letter A designates the main frame of my device, which is made solidof any suitable material, and is pronged or bifurcated at one end, asshown at I), to be placed upon the arbor or shaft of the saw. In thepronged part of the said frame A are shown three screws, 0, which arefor the purpose of adj usting'and securing the said device to any sizesaw arbor or shaft. At the opposite or outer end of this main frame A isa slot, (1, the purpose of which will be hereinafter more fully setforth.

B represents a slide, having shoulder e and arm (1. This slide Bcarriesa bolt or screw, 0, which extends out through the slot 01 in the mainframeA and serves as a guide in the backward and forward movement of thesaid slide.

1) represents a thumb-screw for securing the said slide to the mainframe A, and serves to hold the same down firmly upon the said mainframe at any desired distance from the saw-arbor. E is also a slide orstud, which is placed in rear of the slide B upon the main frame andsecured thereon by means of the screw E, which passes out through theslot d of the said main frame. This slideor stud E carries a screw, 9,which serves as a support or back bearing for the slide B, and assistsin preventing the same from moving backward when the machine is inoperation. The letters H H represent bearing-plates for the screws D andF.

G represents the file,which is placed against the shoulder e of theslide B and held down upon the main frame with the arm (1 of the saidslide by means of the screw D.

The letters in and 12 represent screws,which are for the purpose ofsteadying the saw-blade in the jointer-fraine.

The operation is as follows: The forked portion of the frame A is placedupon the arbor or shaft of the saw, when the blade will extend upbetween the arm d of the slide B and the main frame A. Thesteadying-screws m and n are then screwed down to suit the thickness ofthe blade and prevent any lateral movement of the same while beingjointed. The opposite end, I, which may be provided'with a suitablehandle, is held by the operator, the screw D loosened, and the slide B,carrying the tile, moved up to the teeth of the saw-blade. The screw Fis then loosened and the stud E moved forward a suitable distance towardthe slide B. The screws D F g are then tightened in the manner beforestated, when all the parts will be securely held to the main frame andthe jointing ready to be effected when the saw is put in motion.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The frame A, having forked end I) and slot d, and carrying screws 0and 22, in combination with slide B, carrying screw m, guidebolt 6,thumb-screw D, and plate H, all substantially as and for the purposesspecified.

2. In a circnlar-saw-filing machine, the frame A, constructed asdescribed, carrying screws 0 and n, in combination with the slide B,carrying screw m, the. screw D, bolt 6, screw F, and stud E, carryingscrew G, all substantially as and for the purposes specified.

In testimony that I claim the foregoing as my invention 1 have hereuntoaffixed my hand and seal this 4th day of August, A. D. 1881. v
